Defmod error.

Hello,
I've read the other posts about DEFMOD but none seem to help, the thing is, I only see set default WHM theme, and basic cpanel/whm setup, but I do have root access, I've contacted my host they say they're "working" on it, but I doubt it, root access should be able to see all the things what's been described to fix it I'm sure. Anyway, I get this error "Missing DEFMOD Config Line in /etc/wwwacct.conf " my default WHM theme is "x" maybe you could help me to allow myself to see the things I need to see to fix it, I dunno, but please help, clients are waiting.
